The state law approved in May 2011 required voters to show government-issued photo identification, which could include a driver’s license, a military identification card, a birth certificate with a photo, a current U.S. passport, or a concealed handgun permit.

The Justice Department said that data from Texas showed that almost 11 percent of Hispanic voters, just over 300,000, did not have a driver’s license or state issued identification card, and that plans to mitigate those concerns were incomplete.

“Hispanic registered voters are more than twice as likely as non-Hispanic registered voters to lack such identification,” Assistant Attorney General Thomas Perez said in a letter to the Texas director of elections outlining the objection.

This is the second state voter identification law blocked by the Obama administration, which earlier objected to a strict new law in South Carolina that it prevented from taking effect. South Carolina then sued in federal court seeking approval of its law.
